- Specification of Letters Patent.

Application filed November 25, 1911.

Patented July 2, 1912.

Serial No. 662,311.

To all wltom it may concern:

Be it known that I, DICK B. l/VILLrAMs, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Bundling-Machines, of which the following is a specifieation.

The present invention relates to certain new and useful improvements in the construction of bundling presses such as are adapted to be employed for holding laths, and similar loosemembers, in a compact bundle while wrapping the same with some binding medium such as a wire or cord.

The object of the invention is to provide a bundling machine which may be easily operated, which comprises few and durable parts, and which will hold laths or similar members in a very tight and compact bundle.

A further object of the invention is to provide a bundling machine which embodies novel features of construction whereby the bundling arms may be easily and quickly locked in a closed position or released therefrom, as may be desired.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain novel combinations and arrangements of the parts, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following de' scription and accompanying drawings, in which:

Figure 1 is a perspective View of a lath bundling machine constructed in accordance with the invention. Fig. 2 is a vertical transverse sectional view through the same, the jaws being shown in an open position. .Fig. 3 is a similar view with the jaws in a closed position. Fig. 4 is a detail view showing one of the spring actuated plunger-s which normally tend to close the'jaws. Fig. 5 is a detail view of one of the cam shoes, and Fig. 6 is a' detail view of one of the plates to which thelower ends of the links or toggle members are connected.

Corresponding and like parts are referred to in all of the figures of the drawings and designated throughout the following description by the same reference characters.

. Specifically describing the present embodiment of the invention, the numeral 1 designates a base upon which the bundling machine is mounted. A pair of similar standards 2 which have a spaced and parallel relation to each other project upwardly from the base, the lower end of each of the standards being formed with the feet 3 which are secured to the base in some suitable manner, while the upper end of the standard is formed with a notch or seat 4 adapted to receive a bundle of loose laths or similar members. A pair of bundling arms or jaws 5 is provided for each of the standards 2, the said jaws being pivoted upon the ends of a cross bar 6 which is slidably mounted within vertical slots 7 formed in the upper ends of the standards 2 just below the lath receiving seats 4. Each pair of bundling jaws 5 is shown as arranged upon the outside of the standard and as held between the standard and a set collar 8 applied to the cross bar. The bundling jaws 5 of each pair are reversely curved and project upwardly above the respective seat 4 so as to grip a number of laths or like parts upon the seat and force them into a tight and compact bundle. One of the bundling jaws 5 of each pair is provided with a wire tying and cutting device 7 for securing and severing the ends of the binding medium which is employed for holding the laths together,

said device being preferably the device covered by my Patent No. 1,004,514, dated Sept. 26, 1911.

The lower ends of the bundling jaws 5 cross each other and are provided with the downwardly projecting and diverging extensions 5, the ends of the said extensions being connected by means of links or toggles 10 to a cross bar 11 which is slidably mounted in vertical slots 12 formed in the lower ends of the standards 2. In the present instance spider plates 13 are secured to the ends of the cross bar 11, the said plates being formed with the arms 13 to which the l nks 10 are pivoted, and also with the pro ectlons 12 which are received within the slots 12 to retain the plates in an upright posltlon.

The cross bar 11 is received loosely within slots 14 formed in the sides of a treadle member 15 at an intermediate point in the length thereof, one end of the treadle being pivoted upon a shaft 16 connecting the standards 2, while the opposite end of the a treadle is formed with a foot plate 17. It will thus be obvious that when the treadle is raised, the links or toggle 10 will operate to separate the bundling jaws to admit of a number of laths or like parts being placed upon the seat 4 at the upper end of the standards, while when the treadle is lowered,

the links 10 will operate to force the bundling jaws 5 together, so as to compress the laths or like members into a compact bundle.

The upper cross bar 6 is normally held at the top of the slots 7 by means of spring actuated plungers 18. These plungers 18 are pendent fiom plates 19 which are fitted loosely upon the cross bar 6 and held: against the inner faces of the respective standards 2 by meansof set collars 20. The lower ends of the plungers' 18 pass through forked lugs 21 projecting inwardly from the standards, coil springs 22 being interposed between the plates and the lugs. These plungers impart a yielding action to thejaws and enable the-m to readily accommodate themselves to slight variations in the sizes of the bundles.

.The invention also contemplates the provision of means for locking the bundling jaws in a closed position. For this purpose, the lower cross bar 11 is provided upon each side of the treadle 15 with a cam shoe 2?),

the said cam shoes being provided with projections 23 which are loosely received within the slots 12 to hold the shoes in an upright position. A cam shaft 24 connects the standards 2 at a point above the slots 12 and has a pair of cam members 25 pendent therefrom, the said cam members dropping by the action of gravity into engagement with the cam shoes 23. Levers 26 project forwardly from the cams 25 and are connectedv by a cross bar 27, the said cross bar con- 'stituting a convenient handle for raising the cams into an inoperative position. When the treadle 15 and cross bar 11 are raised so as to open the bundling jaws, the cam shoes are caused to engage the inner sides of the cam members so as to hold thecams in a raised position. However, as soon as the treadle and cross bar 11 have been lowered to close the bundling jaws, the cam members 25 swing over the cam shoes 23 by the action of gravity and cooperate with in a closed position, thereby minimizing,

the labor required for bundling the laths and greatly increasing the capacity of an operator.

A feature of practical importance, in carrying out this invention, resides in associating with one arm of each pair of the bum Having thus described the invention,

what I claim as new and desire to secure by Letters Patent, is
